Introduction

About this Book

This book is about hands-on information documented to illustrate the use of LGT8F328P chips that tested and run successfully on Arduino sketch projects using Arduino C/C++ programming language.

In the learning of Arduino platform and compatible microcontrollers, there often lack of information, incomplete online help comments, circuitry implemented may not be the same result as the original circuit diagram and many different MCU libraries required to compile sketch, where can easily forgotten.

Therefore, I decided to write this book to document steps that went through before and solutions found. It is not perfect, but with necessary guidelines to get through and move on.

LGT8F328P LQFP32 and SSOP20 MiniEVB were adopted in this book as to facilitate the learning process, and we do want to build something optimum at the end.

To understand this book, reader should be familiar with Arduino IDE, basic electronics fundamental, PCB design and C/C++ software programming

About the Author

Ricky Gai is the founder and technical director of Nexuz Innovation, a small R&D IT company established in Kuala Lumpur, Malaysia.

After receiving certification from Oxford Computer Engineering discipline in 1992, my carreer was mostly exposed to C/C++ system software development for decades about 30 years, since the MSDOS time until today’s Windows environments including real-time, networking, file system, 2D/3D games, software driver, application and mobile programming.

Nevertheless, much spare time devoted to further the electronics studies for two years before coming to Arduino platform, and my wife often staring at me. Arduino programming reminded me the MSDOS season, it brought back memory of something like interrupt, vector and bootsector ( eg. Bootloader in Arduino ).

All the reference materials and source code are available via Github at:

Well, passion is everything and the key to success, I hope you find something useful here.
